the vast middle is made up of people like me that would be satisfied with a Norway type deal
Evidence for this please - I actually think rather few people would be happy with a Norway-type deal, given that 48% want to remain part of the EU, and the 52% of brexiteers is deeply split - we keep being told that most thought stopping FOM to be the biggest issue, which isn't compatible with a Norway deal.
And this is actually the critical problem - as soon as an actual deal emerges any sense of a mandate vanishes, because it only takes 2% of the leave supporting population to oppose that particular deal for the majority for brexit itself to vanish.
, there are the extremists like yourself and Farage who won't be happy.
On what basis am I an extremist - my views reflect 48% of the country as per the referendum, and over 50% according to all the recent polling which indicates a majority to believe that Britain was wrong to vote for brexit.
Besides Farage would be campaigning for a vote where the options will be no deal or leave, he will not campaign for a third option, stay.
He might, but the notion that a deal and no deal were actually options was always nonsense - we cannot have no deal as there all sorts of things that cannot not be agreed as there is no 'default' solution. The 3 big issues in the preliminary talks being three examples.
